Keyholding and Alarm Response

Are your alarm bells ringing?

"Your company intruder alarm goes off at 2am on a cold and wet Sunday morning. It's your responsibility to attend so your family life gets disrupted yet again. It's probably only a false alarm, but you never know...."


Does this scenario sound familiar?


Well that's where we come in.  As a professional keyholding and alarm response company, dealing with your alarms at unsociable hours is exactly what we do.


We have officers out on the road all night undertaking mobile patrol duties so when they get the call about an alarm, they are awake, alert and ready to deal with the situation.

So why use a keyholding company?

As well as saving you from having to get out of bed at 2am on a cold, wet Sunday morning, there are other advantages to using a professional keyholding company to respond to your alarms.


  • It removes the risks - just imagine if you had a real intruder?
  • A response is available 24/7 - no nights off or holidays
  • We're trained and experienced - we know what to look for
  • We're trustworthy - all of our team are vetted and screened
  • Detailed reporting - all the information you need for your records
  • We operate from Chichester to Brighton and north to Crawley so we're already out and about in your area
  • Fast response times because we keep our vehicles local in Sussex

You can trust us with your keys.

Our clients trust us with the keys to their buildings and we really appreciate how important that is so we take really good care of them. All of our keys are secured and audited in accordance with BS7984 - but what does that really mean?


  • Keys are stored on tamper evident tags and in tamper evident pouches so we always know when your keys have been accessed.
  • Keys are only labelled with a site number (no names or addresses), so should they fall into the wrong hands, they won't be linked to your building.
  • Keys are regularly audited, with each tamper evident seal being barcoded, serially numbered and recorded on our GuardTools database.
  • Keys are either always carried by our officers, or are stored in a specially designed safe which is bolted into the main body of our security vans.
